Not Ranked
"do not use diesel oil in a gasoline engine, the additive package is incorrect. this is not 1975 anymore."
Shell Rotella T 15/40 currently includes these API ratings for spark ignition gasoline engines:
SH, SJ, SL and SM. Those ratings are in addition to their compression ignition diesel engine ratings for this same oil.
